Alan Stern c753113ae7 USB: Skip endpoints with 0 maxpacket length ... [ Upstream commit d482c7bb05 ] Endpoints with a maxpacket length of 0 are probably useless. They can't transfer any data, and it's not at all unlikely that an HCD will crash or hang when trying to handle an URB for such an endpoint. Currently the USB core does not check for endpoints having a maxpacket value of 0. This patch adds a check, printing a warning and skipping over any endpoints it catches. Now, the USB spec does not rule out endpoints having maxpacket = 0. But since they wouldn't have any practical use, there doesn't seem to be any good reason for us to accept them.
